Filed: 1988-11-07
Abstract: PURPOSE:To improve the quality of a lens by using an injection needle and an air- bleeding needle and by providing an elevation tool for elevating the air-bleeding needle after the injection needle is drawn out. CONSTITUTION:Cylinders are operated simultaneously, a contact member 7 is brought into contact with a peripheral wall member 12 and the fore end part of an air-bleeding needle 9 is made to pierce the member 12, while a cut hole 13 of the needle 9 is stopped at a position whereat it faces the inside of the member 12. Next, a lens composition material 4 is filled up in a cavity 2 of a mold through the needle 6, and the air in the cavity 2 is released from the hole 13 into the atmosphere through an exhaust pipe 49. When the level of the material reaches a prescribed height, injection is stopped and the composition material 4 is filled up in the cavity 2 without any air gap. Thereafter the needle 6 is drawn out. On the occasion, the composition material 4 in a quantity equivalent to the volume of the needle 6 flows back into the cavity 2 from the hole 13 and, consequently, no gap is formed in the cavity 2. Subsequently an elevation tool is operated to elevate the needle 9 to a position whereat the hole 13 of the needle 9 faces a through hole 42 of the member 7. A shortage of the composition material 4 caused by drawing out the needle 9 is covered since the composition material 4 being present in the needle 9 flows back into the cavity 2, and therefore no gap is formed in the cavity 2.

The value of (y) is set larger than (x), e.g., y=0.8 and delta is not zero. Since superconducting state is originally realized by the influence from outside, superconducting current can be controlled by controlling the above mentioned influence, e.g., the quantity of free carrier to be introduced. Thereby obtaining a superconducting device whose superconducting current is controlled from outside.

Filed: 1990-10-19
Abstract: PURPOSE:To comparatively exactly execute the inclination detection and the correction of a character by deriving an inclination angle of a rectangle of the minimum area whose four sides come into contact with an input character, and correcting its inclination. CONSTITUTION:In a rotation correcting part 22, based on an inclination angle derived by an inclination detecting part 221, an input character is rotated in the direction opposite to an inclination from a reference line by an inclination portion, and the inclination of the input character is corrected. That is, a rectangle whose four sides come into contact with the input character, and which surrounds the input character is generated, that of the smallest area is detected therein, and an inclination from the reference direction of its rectangle is derived. Subsequently, by the rotation correcting part 222, the input character is rotated in the direction opposite to the inclination by its angle portion and subjected to coordinate transformation and the inclination of the input character is corrected by a large normalizing part 223. In such a way, even in the case of a KANJI (Chinese character) whose number of strokes is large, an inclination of the character can be detected and corrected comparatively exactly.

Title: Creep force control method
Inventor: YAMAMOTO TOSHIO
IPC: B60W10/06
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To automatically control a creep force apt to be dispersed according to each product by a simple constitution by effectively utilizing the results of an idle rotation speed control by an idle control means as a sensor indirectly expressing the creep force. SOLUTION: A creep force acting in stopping a brake is not used for traveling a vehicle but reactionally acts as a force lowering the rotation speed of an engine, so that it draws attention that the difference between a control value DFB for holding the engine rotation speed in this state to a target idle rotation speed and a control value stored and learned in an ordinary state without acting the creep force, namely, a learned value DLRN, indirectly indicates the creep force, thus attempting to set the creep force to constant. The memory of the engine controller memorizes a program shown in a flowchart, repeatedly executes it at fixed periods, and automatically controls a clutch mechanism so that the dispersion of the creep force according to each vehicle can be controlled within a tolerance.

Abstract: PURPOSE:To obtain an electronic component for surface mounting use such as a laminated transformer, an in-phase inductor or the like whose performance and reliability are high even under severe surroundings by a method wherein a magnetic layer is formed of a ferrite paste having a mirror-surface whose glossiness is at least 40% at the time of film-formation and drying operation. CONSTITUTION:At this laminated transformer, electrode films are constituted after they have been baked as external electrodes 31A, 32A, 31B, 32B on both edges of a magnetic layer 11 formed of a high-filling and high-density ferrite paste. Conductor parts 12, 13 formed of a conductive paste are formed in the magnetic layer 11. For the magnetic layer 11, a highly dispersive ferrite paste having a mirror-surface whose glossiness is 40% or higher at the time of film-formation and drying operation is used. When the highly dispersive ferrite paste is used, the roughness on the surface is reduced at its film-formation and drying operation, and a high-filling laminated body is formed. When the paste is made dense by a sintering operation to be executed later, it is possible to sufficiently prevent moisture or the like from creeping even when the transformer is used under severe surroundings, and it is possible to sufficiently prevent a phenomenon that a conductor part is damaged so as to damage the reliability of a device.
